How Your Lake Water Is Tested: Inside the Lilly Center Research Lab

In this episode of The Lake Doctor Podcast, we sit down with Annalieze Frentzel, Research Lab Coordinator at the Lilly Center for Lakes and Streams, to put lab research under the microscope and discover the work that keeps lake science moving. Annalieze shares what happens long before published data ever reaches the public—from coordinating lab workflows to supporting research that directly impacts local lake communities. It’s an inside look at the systems and people working quietly to protect water quality in Kosciusko County.The conversation also dives into important public services the Lilly Center provides, like algae toxin notifications and E. coli reporting. Annalieze explains how accuracy and preparedness play a critical role when public health and lake access are on the line. She shares how months of training prepare her college intern team to meet standards of excellence in the research lab. Whether you’re a lake resident, student, or simply curious about how lake science operates day to day, this episode highlights the careful, intentional work happening behind every report and notification.Learn more about the Lilly Center's work at https://lakes.grace.edu/.Have a question we could answer on the podcast?
